This is another maths worksheet for year 5 on standard units of measurement and will show clearly whether the metric system is understood.

The questions ask for fractions of metric units eg half of a kilometre or one tenth of a kilogram. Because it is a metric system finding one tenth or one hundredth of the units is very easy, especially compared to the old fashioned and out of date imperial measures.The tricky bit usually is remembering whether there are 100 or 1000 parts in the whole unit – that just has to be learned. The other complication for some children who relate ‘mille’ with a million, when it is, of course, a thousand.

Counting in tens might seem easy, especially by year 4.

However, there are many children who do find difficulties, especially when crossing the hundreds and thousands boundaries. One such difficulty might show itself if asked to write down ten more than 1097, which is 1107 or ten more than 2896 which is 2906.
Even harder might be ten less than 4006, which is 3996.

Don’t take it for granted that your children can do this as a really good understanding of place value is needed.

It has been a while since I posted anything for year 4 so here is a maths worksheet on addition. It is good revision of the terms: ‘What is the sum of…’, ‘What is the total of…’, ‘How many altogether?’ and ‘increase….by…’.
These terms should all be familiar to children in year 4 and they should be able to carry them out in their heads.
When adding three numbers in your head it is a good idea to start by adding all three tens and then adding on the units eg
25 + 36+ 51.

Add the 20, 30 and 50 to make 100.
Then add 5 to make 105, then 6 to make 111 and finally 1 to make 102.
Note this is by all means not the only way to do it!

1000 is a very large number for children working in Year 3 and one which is difficult to imagine the size of. The sheet asks how many different ways can two numbers be added to make 1000, using only whole hundreds.To be able to do this children need to be confident with their numbers up to 10 and be able to know which pairs of numbers add up to 10.

As an investigation it is very similar to asking how many ways can 100 be made only using whole tens.

Many children find it harder to count back than count on. This is quite a simple page as it does not involve counting back through a whole ten. Sometimes children will count back using their fingers. Hopefully as confidence grows they will be able to see some answers straight away, eg Count back 5 from 46 is 41 because they have remembered that 6 – 5 is 1.

Here is a follow up to a simple number investigation using 3 boxes and some buttons. It looks at how many different ways 10 buttons can be placed in 3 boxes.

Much the best way to do this is practically and it is a suitable activity for children much older than Year 1. It allows for the making of rules eg can I put all ten buttons in one box and leave the others empty? it also encourages logical thinking and careful recording to ensure that the same combination is not repeated.
